The facility to mark a lot of invoices for DD and then submit them all in one go is fabulous - just one little extra feature please! When one or more of those DDs fail could they perhaps be marked in the DD report as having failed? At the moment you are told that one or more has failed, but you have to search through them all to find which one(s)
I believe this should already be the case, when a DD fails GoCardless send a notification to us and we adjust the GoCardless Bill ID status accordingly. Are you able to PM me a particular case where this didn’t happen?
